Got a new APE CCT installed at the shop (afraid I would fu** it up), and the mechanic said it was adjusted pretty tight. I started it up, sounded fine at the shop, but once it warmed up on the way home, slowly started ticking. Same this morning on the way to work, about 5 minutes it started and slowly got louder. The ticking directly reflects engine RPM, and you can hear throughout the rev range. I don't hear any chain slap or dieseling sound like valve clatter, just a steady tick than can be heard from idle to redline. It's pretty loud, you can hear it riding through the wind and exhaust. Wierd thing is, you can hear it easier from the left side of the engine, but maybe that's just because the exhaust is on the right. I figured maybe it was just loose, but I'm afraid to tighten it more since the mechanic already said it was pretty tight. Also, never heard it before the APE install, so I'm pretty sure that's got to be it. But I wanted to check with you guys for your opinions. Thanks!
